See 0dcac9c3

If the source is using a custom IO, setting this flag causes heavy leaks
since the segments will not have their avio context closed.

Regression since f5da453b.

Using AVOnce as a stack variable makes no sense as the state is lost
when the function exits.

This fixes repeated calls to av(filter/device)_register_all

It was broken in 091c9860

Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.

This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).

Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
